They Live

A homeless drifter discovers a reason for the ever-widening gap between the rich and the poor: a conspiracy by non-human aliens who have infiltrated American society in the guise of wealthy yuppies.

With the help of special sunglasses that reveal the aliens' true faces and their subliminal messages ("marry and reproduce," "submit to authority"), our hero tries to stop the invasion. This satire of Reaganomics and the "greed is good" era also has one of the funniest (and longest) fight scenes in American cinema.
